Ingredients You’ll Need
For the Soup Base:
- 3 lbs Russet potatoes, peeled and diced into 1-inch cubes
- 1 medium yellow onion, diced
- 3 cloves garlic, minced
- 4 cups chicken broth (low sodium is best so you can control the salt)
- 1/2 teaspoon dried thyme (or Italian seasoning)
- 1/2 teaspoon black pepper
- 1 teaspoon salt (adjust to taste)
For the Creamy Finish (Add at the end):
- 1 cup heavy cream (or half-and-half for a lighter version)
- 1/3 cup all-purpose flour (optional, for extra thickness)
- 1 cup sharp cheddar cheese, shredded
- 1/2 cup sour cream
The « Loaded » Toppings:
- 6 slices of bacon, cooked until crispy and crumbled
- Fresh chives or green onions, chopped
- Extra shredded cheese
- A dollop of sour cream
Step-by-Step Instructions
Step 1: Prep the Veggies (10 Minutes)
Peel your potatoes. While some recipes say you can leave the skin on, for a truly creamy « restaurant-style » soup, I recommend peeling them. Dice them into uniform 1-inch cubes so they cook evenly.
Dice your onion and mince the garlic.
Why Russet Potatoes? They have a high starch content. As they cook, they naturally break down and thicken the soup, creating that velvety texture we want. Waxy potatoes like red potatoes will hold their shape too well and leave the broth thin.
Step 2: The « Dump & Go » (5 Minutes)
Place the diced potatoes, onion, and garlic into your 6-quart slow cooker. Pour the chicken broth over the top—it should just barely cover the vegetables. Sprinkle with thyme, salt, and pepper. Stir gently to combine.
Cover and cook on LOW for 6-8 hours or HIGH for 3-4 hours. You’ll know it’s done when the potatoes are fork-tender and starting to fall apart at the edges.
Step 3: The Thickening Hack (Important!)
About 30 minutes before serving, it’s time to make it creamy.
In a small bowl, whisk the flour with the heavy cream until smooth (this prevents lumps). Pour this mixture into the slow cooker and stir.
Pro Tip: Use a potato masher directly in the pot to mash about 1/3 of the potatoes. This is the secret to a thick, hearty soup without needing tons of heavy cream or cornstarch.
Stir in the sour cream and the cup of cheddar cheese. Cover and cook for another 20-30 minutes until the cheese is melted and the soup has thickened.
Step 4: Serve & Top
Ladle the soup into bowls. Now comes the fun part: toppings! Be generous with the crispy bacon, green onions, and extra cheese. This is what turns a simple potato soup into « Loaded Baked Potato Soup ».

Customization & Variations
Make it Vegetarian: simply swap the chicken broth for vegetable broth and skip the bacon topping (or use smoked paprika for that smoky flavor).
Add More Protein: Stir in leftover diced ham or shredded rotisserie chicken during the last 30 minutes. Ham and potato is a classic combo that works beautifully here.
Spice it Up: Add a pinch of cayenne pepper or a diced jalapeño with the onions for a « Southwest » twist.
Gluten-Free: Skip the flour. The potatoes will naturally thicken the soup enough if you mash them well. Ensure your broth is GF certified.
Common Mistakes to Avoid
Mistake #1: Adding Dairy Too Early
Never add milk, cream, or sour cream at the beginning of the cooking time. High heat over long periods causes dairy to curdle and separate, giving your soup a grainy texture. Always add it in the last 30 minutes.
Mistake #2: Undercooking the Potatoes
If your potatoes are still hard in the middle, the soup won’t be creamy. Be patient. If you’re in a rush, cut the potatoes smaller next time.
Mistake #3: Freezing with Dairy
Dairy-based soups tend to separate when frozen. If you plan to freeze this, scoop out the portion before you add the cream/cheese in Step 3. Add the dairy when you reheat it.
Serving Suggestions
This soup is hearty enough to be a main meal. Serve it with:
- Crusty sourdough bread for dipping
- A simple green salad with vinaigrette to cut the richness
- Garlic knots or breadsticks
- Roasted broccoli on the side
How to Store and Reheat
Refrigerator: Store leftovers in an airtight container for up to 4 days. The soup will thicken significantly as it cools.
Reheating: You’ll likely need to add a splash of milk or broth when reheating to get the consistency back. Microwave in 1-minute intervals, stirring in between, or reheat gently on the stove over medium-low heat.
Final Thoughts
This Slow Cooker Potato Soup is more than just a recipe; it’s a winter survival strategy. It’s economical, effortless, and universally loved. Whether you’re feeding a family of six or meal prepping for one, this bowl of comfort never disappoints.
